Automower winter storage: battery, charging station and wires

01Choose the storage place before the last mow

A shed is only a suitable winter home if conditions inside it meet the mower’s requirements. Check for frost and damp rather than relying on the word “indoors”. Husqvarna’s temperature guidance lists 0–50°C for storage and 0–45°C for charging, while its winter guide calls for a dry, frost-free storage space. Your exact manual takes precedence.

Decide when to finish mowing from local conditions and grass growth. A mower’s operating temperature range is not a recommendation to drive it across a frosted lawn. Husqvarna notes that grass is particularly vulnerable to wear during frost.

02Finish charging, then switch the mower off

The 305E/310E NERA manual instructs owners to charge fully before storage, switch the product OFF and clean it. Do not treat a parked mower as proof that it has been switched off.

Husqvarna’s general winter guidance says most models do not need charging during storage, but some older models need it every three months. Look up your model before creating a charging reminder. This is not a reason to leave every Automower connected to a charger all winter.

03Clean without assuming every mower can be hosed

Husqvarna prohibits high-pressure washing of the mower and station. Permission to use ordinary running water depends on the model, and the mower and its charging station can have different rules. For example, its cleaning guidance permits running water on a 310 Mark II mower but not its station; listed NERA models permit both.

Use the approved cleaning method, with the mower switched off and the station power disconnected before cleaning the station. Remove accumulated grass and inspect accessible parts for wear or damage. Wear protective gloves around blades. Our related cleaning guide below compares model families; use your manual for the complete procedure.

04Separate the NERA baseplate from the station top

For the 305E/310E NERA specifically, section 9.3 of the March 2026 manual allows the baseplate to stay outside while the station top and power supply go into dry, frost-free storage. It includes disconnection, removal of the cable grommet and closing a sealing lid. Follow the illustrated sequence; do not simply pull the top off.

That removable-top procedure is not a universal instruction for older stations. Husqvarna generally recommends indoor station storage. If a station must remain outside, its winter guide describes keeping power and boundary/guide wires connected with weather protection. Confirm that arrangement for your model before choosing it; it is a different plan from dismantling the station.

05Label wires; preserve the EPOS reference position

Boundary and guide wires can remain in the ground. Label disconnected ends and protect their connectors using the manufacturer’s storage arrangement.

For EPOS installations, Husqvarna permits the reference station to stay outside with power connected. If taking it inside, keep its mounting arm in position so it can return to the original location. Moving the reference position can mean recreating the virtual boundaries.

06Leave a short, useful handover to your spring self

Use this final record to expose unfinished work. It is an organisational checklist, not a substitute for the model’s storage procedure. Mark an item “pending” when you have not verified it.

• Model and manual: __________
• Final charge and shutdown completed on: __________
• Cleaning completed; repairs still needed: __________
• Mower location: __________
• Station parts and power supply location, or approved outdoor arrangement: __________
• Wire labels and EPOS reference position recorded: __________
• Storage charging required by this model? If yes, next date: __________
• Spring reminder: reconnect using the manual, check the schedule and inspect the installation before the first run.

07Worked case: a storage plan you can actually reverse

Illustrative scenario: a household can store the mower in a dry room, but plans to leave the station at the lawn. Write two decisions rather than one “put away” tick: where the mower goes, and which station arrangement the exact manual permits. If a NERA station is involved, identify the baseplate and top in the manual before treating them as separate storage items.

Create an inventory as parts move. Give each approved removable item a bag or shelf label and photograph the connections before disconnection. “Power supply: garage shelf B” is a useful entry; “all accessories stored” is hard to verify in spring. Do not put PIN codes, account passwords or precise home-location details on a public or shared record.

Leave pending work visible. For example, “charging completed; wheel resistance still needs assessment” is a more honest handover than a completed winter checklist with no exception. Keep model-specific storage charging instructions alongside the storage date. When restarting, use that record to restore the correct arrangement before testing normal operation.
